Mercedes-Benz Planning New Sports Car Based On SLS AMG

The Porsche 911 better look out because Mercedes-Benz is reportedly working on a new sports car based on a shortened version of the 2010 SLS AMG’s platform targeted directly at it. The new Mercedes-Benz sports car will copy the SLS AMG’s aluminum construction but will lose the funky gullwing doors.

Instead, conventional front-hinged doors will be adopted in an effort to bring costs down. The new model will also pick up AMG’s next-generation V-8 engine, a 5.5-liter unit with direct-injection and turbocharging technologies and an output of around 500-horsepower. Acceleration times for the 0-60 mph dash are expected to fall around the 4.5 second mark.

The new sports car is tipped to be called the SSK AMG and is due for launch in 2014--an open top roadster version is an almost certainty.

The decision to build more standalone AMG models is to help establish the Mercedes-Benz in-house tuner as a separate sports car manufacturer that could eventually rival other smaller players in the supercar arena such as Pagani and McLaren.

Renault Alpine Sportscar

While Renault car sales in France have been robust in the first half of 2008, in Europe – its biggest market – the group is down 4.6 percent. If higher sales and better market penetration is the question, could a sports coupé be the answer? The Cartribe reckon Renault thinks so. They say after an interview with one of Renault’s highest-ranking officials, news was revealed to them of a sportscar similar to the Nissan’s 350Z will be on sale by 2010.

Underpinning this vehicle would be an Infiniti G37/ Nissan 370 Z base, which we think wouldn’t be a lame idea in the least bit, given the outstanding handling characteristics of these two cousins. Moreover, the name Alpine would be the one to carry a sports Renault. You know the name from decades ago when it used to build winning racing cars using Renault engines. Although WCF reported on such a car a few weeks ago, it has been very much a rumour. Up until now.

A Renault proper sportscar we suspect would use a relatively small turbo engine rather than a large V6 block for obvious reasons; weight, compactness, emissions and a possible return of the turbo to Formula One. The car will not be based on any existing Renault car and will be quite different, even radical in styling. Renault desperately needs to justify its multi-million-Euro involvement in F1 and so far, as good as RenaultSport is, it hasn’t happened to the extent desired.

Mazda RX-7 to mark the end of RX-8 in 2011

Mazda Taiki Concept

While Toyota works on getting its FT-86 rear-wheel-drive coupe on the road and as Nissan plans a rival, another Japanese automaker is going to throw its two cents into the segment as well. Sources close to Mazda say that RX-7 should see a revival sometime in early 2011 and will mark the end of the slow-selling and expensive RX-8.

The next-generation Mazda RX-7 will use the company’s new Renesis 16X rotary engine, which made its debut in the Taiki concept. While the 16X is capable of producing 350-hp and 215 lb-ft of torque, Mazda will keep output around the 200-250 range in order to stick the price-tag close to $25,000.
